For folk looking to get a hands-on intro to graphical app development with Go and Fyne this session is for you.
Everything from getting started, through building an app onto your computer and on to customising the toolkit and building your own widgets. You'll learn everything you need to build the app of your dreams. :)

LEVEL: Introductory or Overview

In this journey through secure software development, you'll learn and practise defensive coding approaches that will enable you and your team to write safe code without even thinking about security.
We will walk through classes of issues and see how to prevent vulnerabilities from seeping into code.

LEVEL: Intermediate

This hands-on workshop will take a simple legacy cloud native application with no coverage and will show the common techniques and tools to gradually introduce coverage, to make the application behavior deterministic and without regressions.

“ The only easy day was yesterday. ”, Revisiting your past Programming Fears/Challenges/Experiences with a Different perspective and Mindset.

LEVEL: Intermediate

A couple of years ago, I worked on a project with high scalability and resiliency requirements. Event-driven architecture would be the perfect fit there. Unfortunately, nobody else on the team felt comfortable using event-driven architecture. I asked myself: "What can I do to make building event-driven applications as simple as an HTTP server?". This was the moment when Watermill was born.

A couple of years later, Watermill became the most popular Go library for building Event-Driven applications, used by numerous companies, more than 50 contributors, and over 6k stars on GitHub.

LEVEL: Advanced

This talk introduces a method to enhancing the security of software projects by seamlessly integrating Seccomp profile generation into the test pipeline. This methodology emphasizes comprehensive test coverage of the application, encompassing both integration and unit tests.

LEVEL: Intermediate

Have you ever debugged a little too hard and reached the Go runtime? If so, and if you continued digging deeper, you may have reached the unwinder - an internal runtime type responsible for unwinding stack frames. In this talk we’ll understand exactly what that means, how it works, and where it’s used. This is an opportunity to learn about the internals of the language you code in and discover how to improve performance with knowledge of stack resizing, GC, and more.

LEVEL: Advanced

During this talk I would summarize the cases where the synchronous communication is the right choice and on contrary where it is causing problems and it is better to pick the asynchronous one. Throughout the presentation I will combine the slides with actual code comparing the two principles on real simple examples to let the listener to better imagine the impacts. I will show how it is easy to implement load balancing/throttling/rate limiting to prevent go apps from overwhelming just by switching to asynchronous communication. Also the implementation of retries mechanism will be shown as one example where asynchronous communication may be used. For the examples I will use regular Http server written in go as a example of synchronous code and consumers using RabbitMQ and PGQ to cover the asynchronicity. The summary of the talk will be, that before designing some feature, you should think twice, whether it is not better to do design it in asynchronous way. And if you decide it is better to make it asynchronous, that it is not a big deal to actually implement it in Go using already existing tools and libraries.

LEVEL: Intermediate

On the boundaries of our programs lives the realm of raw bites. This talk presents a collection of nuance-increasing strategies to keep the chaos at bay.

LEVEL: Intermediate

Have you wondered how terminal shells work? Do you want to create your own programming language? This talk is for you! We will look at Elvish, a shell and built in Go with a full-fledged programming language. We will dive into how its implementation as well as testing and CI/CD strategy.

LEVEL: Intermediate

After a decade or more where Single-Page-Applications generated by JavaScript frameworks have become the norm, we see that server-side rendered HTML is becoming popular again, also thanks to the emergence of libraries such as HTMX or Turbo. Writing a rich web UI in a traditionally server-side language like Go is now not only possible, but a very attractive proposition.

LEVEL: Intermediate

Get ready to witness a code transformation that's more exciting than watching a hedgehog unfurl! Generics in Go were introduced in March'22, but aside from scratching the surface, there haven't been many presentations about using them on a larger scale. In my talk, I will explore the challenges we faced, how we used clever generic design patterns to overcome them, and the benefits we gained.

LEVEL: Advanced

This session will provide a detailed introduction to WASI and its integration in Go, using live coding examples. It will also explore how Go applications can utilize WASI and networking extensions for creating robust WebAssembly applications. Attendees will gain a thorough insight into developing and deploying Go applications with WASI.

This session will demonstrate how to automate a dog's daily routine using Arduino and TinyGo, with a real-life example of opening a kennel door and releasing dog food. Attendees will learn the benefits of using TinyGo, and how it makes development more approachable compared to traditional Arduino programming. By the end of the talk, attendees will have a solid understanding of how to use Arduino and TinyGo in their own automation projects (for pets and beyond).

LEVEL: Intermediate

Nix the package manager has gained a lot of popularity in the last 18 months or so. I would love to be able to show other gophers, how they can leverage Nix and its ecosystem to improve their development environments.

Including how we can use it to create more consistent development environments, between different devices and other engineers. So we get the same development environment and tooling as each other. Then how can we use it in CI, Go have essentially the same local development environment and CI development environment. Avoiding the dreaded “it works on my machine” meme.

Golang is the perfect language to pair with Nix because of how simple it is to set up with Nix. Due to it having some great tooling already. We will see, we can replace some of our existing tooling to manage developer environments with Nix.

LEVEL: Intermediate

In the past 6 months, my team encountered two critical incidents stemming from the same root cause - complete power loss in one of our primary data centers. The incidents occurred 5 months apart, and although the root cause was the same, our services responded very differently the second time around. Drawing from lessons learnt from this, this talk dives deep into the strategies and techniques implemented to build ultra-resilient systems in Go.

LEVEL: Introductory and Overview

Unlike other languages, the tools Go offers out of the box for unit testing our applications are pretty comprehensive.
The audience will walk away with a set of new techniques to write more coherent and understandable tests that fit well in a Go project.

LEVEL: Introductory and Overview

Regardless of your interest in database development, this talk guarantees valuable insights into leveraging the capabilities of Golang for crafting scalable and performance-critical applications.

LEVEL: Intermediate

The outline of the talk should go this way
- Introduce myself and my passion for board games
- Explain the game Ticket to Ride and why I decided to implement it in Go
- Show the creation of a Ticket to Ride board in Go
- Explore some Graph algorithms that can give us some insights on
- If time permits also show some gameplay examples

LEVEL: Introductory and Overview

We will discuss which behaviors we should avoid, how to initiate and lead architectural discussions, and how to express these intentions in Go. We will start with issues with large pull requests, being too excited with solutions, and ivory tower architects. Next, we will move on to keeping decision records and diagrams, confronting our biases, and approaching the problem differently. In the end, we will do a live coding session to continue the discussion with future developers reading our code: using type aliases, interfaces, internal folders, and project structure.

LEVEL: Advanced

Being able to debug your code in the IDE should be an easy process. If you ever struggled with debugging Go code in Visual Studio Code, this session is definitely for you. We'll take a look at how to debug several kinds of projects by only tweaking settings in the dreaded "launch.json" file. You'll discover how many options and customizations you can apply to this file to leverage your debugging experience. Finally, we briefly touch on the key features of the Delve debugger.

LEVEL: Introductory and Overview

Whenever you compile a program in Go, it generates a binary that contains your program, but... what is there?
Of course there the compiled version of your code, but what else?
Come with me to explore the inside of the go binary, the elf sections, and how they are used by our executable.

LEVEL: Advanced

Attendees will learn about Go's toolchain, particularly the `go build` command, and how environment variables such as `GOOS` and `GOARCH` are used to specify the desired target operating system and architecture. We will explore practical examples of cross-compiling Go applications for various platforms, including Linux, Windows, macOS, and ARM-based systems.

The talk will also address common challenges and best practices in cross-compiling, such as handling platform-specific dependencies, managing external libraries, and optimizing binary size and performance. We will showcase tools and techniques to streamline the cross-compilation process, including the use of Docker for creating reproducible build environments.

By the end of this session, participants will have a comprehensive understanding of how to effectively cross-compile Go programs, enabling them to deliver consistent and reliable binaries across diverse platforms with ease.

GIF animation icons enable users to express themselves much better. Resizing animated GIFs is necessary to support them.
What would you use when implementing GIF resizing in your Go web application? ImageMagick as we did? Another CLI? Or a C library wrapper?
There is little knowledge of GIF resizing in Pure Go. There are articles about basic image resizing, but they don't cover animated GIF-specific processing. Therefore, popular methods to implement it are using CLIs or C library wrappers.
However, those invoke several unignorable issues. Calling CLIs directly from the code causes security concerns. Image-processing CLIs and C libraries are typically large files that don't fit into a container environment. Also, they cause performance overheads that affect app latency.
Stop using them by implementing GIF resizing with pure Go! It requires some specific knowledge, but it's so simple that we can implement it with only standard libraries and sub-repositories (golang.org/x libraries)!
Learn how to implement GIF resizing with pure Go step by step and the cautionary points you may face during the implementation.
